("Old MTCH"), IAC Holdings, Inc. ("New IAC"), a direct wholly-owned subsidiary of Old IAC, and Valentine Merger Sub LLC, an indirect wholly-owned subsidiary of Old IAC. On June 30, 2020, the businesses of Old MTCH were separated from the remaining businesses of Old IAC through a series of transactions that resulted in the pre-transaction stockholders of Old IAC owning shares in two, separate public companies—(1) Old IAC, which was renamed Match Group, Inc. ("New Match") and which owns the businesses of Old MTCH and certain Old IAC financing subsidiaries, and (2) New IAC, which was renamed IAC/InterActiveCorp, and which owns Old IAC's other businesses—and the pre-transaction stockholders of Old MTCH (other than Old IAC) owning shares in New Match. This transaction is referred to as the "MTCH Separation."
